Battery and fuel cell test load
1470E Solartron Analytical

The mode 1470E is an eight channel potentiostat/galvanostat. Each independent channel within the 1470E is controlled by its own dedicated high performance digital signal processor, which provides accurate and instantaneous test control, data averaging and safety limit functions. A wide range of potentiostatic (voltage controlled) and galvanostatic (current controlled) techniques may be performed, including:

* open circuit
* cyclic voltammetry
* constant level and scanned voltage / current controlled techniques
* fast voltage / current pulse techniques (e.g. for mobile phone cell tests)
* voltage / current step techniques
* linear polarization resistance techniques
* ohmic-drop measurements (for accurate equivalent series resistance ESR analysis)

High-speed data acquisition
The 1470E is able to acquire DC data at 10,000 samples per second, which allows the unit to make very accurate measurements of the equivalent series resistance (ESR) of batteries, fuel cells and supercapacitors using DC ohmic drop techniques. If required, the 10,000 samples per second data acquisition rate can be used in extremely short bursts of 1 millisecond, for example immediately after the cell current is reversed or interrupted in order to measure the ESR. The 1470E can operate at different measurement sample rates at each step in the experiment so high-speed data is only acquired precisely where it is needed and the PC disk is not filled with repetitive data.

The 1470E also provides data reduction and averaging techniques to minimize noise on the data and to reduce PC data storage requirements.
